Postgraduate entrance examination should be investigated from three aspects:
1. own strength. 2. The strength of colleges and universities. 3. Apply for professional college strength.
I don't know which university the subject is in, what major you studied originally, and whether you are in Beijing, master or scum.
But as far as institutions are concerned, Beijing Technology and Business University is still a good platform, with a lot of campus resources and a good location of the school headquarters. From this perspective, Beijing Technology and Business University is definitely not a scum school. As for what level you are talking about, objectively speaking, it will be slightly inferior to capital university of economics and business Dingyi at the same level. However, in terms of specific ace majors, Beijing Technology and Business University also has its own specialty.
As for the business administration major you chose, my humble opinion is that if you really want to learn something, you should rely on "classics" instead of "management". Don't dream of learning dragon slaying earlier. After studying business administration, will there really be enterprises for you to manage? This major is just a platform. If you want to really get close to "enterprise management", you should also learn economic knowledge in a down-to-earth manner, not overnight.
